“…En Israel, el 70% de las aguas residuales tratadas se reutiliza para riego de cultivos. (Matos et al, 2012) Los sistemas BRAC, de origen canadiense con sede en Costa rica, además de recibir agua proveniente de duchas, lavandería, lavamanos y de tinas, cuentan con filtros y una bomba que permiten un óptimo reciclaje de aguas grises, para luego alimentar los tanques de los sanitarios. Estos sistemas permiten el ahorro de aproximadamente un tercio del consumo de agua potable en una vivienda particular.…”

“…Moreover, greywater has a high potential for irrigation because the required quality is not higher than toilet flushing and the plant can take up some nutrients in the greywater. According to Matos [11], household greywater provided enough irrigation for 20 m 2 during months of the dry season, with 11.5 mm day −1 . Greywater reuse has demonstrated efficiency in many regions that are facing water scarcity.…”

The objective of the study was to evaluate the usefulness of novel nonwoven textile filter technology for greywater treatment. This technology had already been used on a lab scale for septic tank effluent treatment; however, this study is the first time it has been used for greywater treatment. The set-up period with septic tank effluent (STE) feeding was significantly shorter than that of greywater feeding. The average capacities of both filter types were practically the same: 1.0–1.4 cm d−1. The relatively high efficiencies of chemical oxygen demand (CODCr) and biochemical oxygen demand (BOD5) removal (58.8–71.6% and 56.7–79.8%, respectively) were obtained thanks to the relatively low filtration velocity and effective diffusion of atmospheric air into the greywater. The relatively high efficiency of total suspended solids (TSS) removal (67.0–88.4%) was obtained by reducing the effective pore size of the filtration layer due to high biomass concentration and accumulation of suspended solids. Thanks to hydrostatic pressure, the filters can work practically with very low energy consumption. The pollutants removal efficiencies were satisfactory in respect to simple construction and maintenance, low investment and operational costs.

“…The intensification of irrigated farming coupled with efficient use of water resources are being advocated by scientists of many countries (Keller and Bliesner, 1990;Laycock, 2007;Matos et al, 2012;Goyal, 2014).…”

Technology and Regime of Sugar Beet Drip Irrigation with Plastic Mulching Under the Conditions of the Jambyl Region

et al. 2016

Understanding the effect of sugar beet plant spacing, irrigation, and mulching on growth, yield capacity and quality of sugar beet is crucial for farmers who work in arid areas under water deficiency. Two‐year experimental field studies were conducted in the arid Jambyl region, South Kazakhstan, to collect experimental data and find the optimal parameters and technology of forming sugar beet yield capacity. During the first year of field studies, different sugar beet plant spacing systems were analysed together with the effect of plastic mulching. The optimal sugar beet planting system, determined by the first study, was used during the second experiment to determine the optimal irrigation regime. The main objective of the study was to find the optimal parameters that provide the highest yield of sugar beet, while being the most efficient in terms of water use. The first field experiment found that the optimal system of sugar beet plant spacing was 20 × 50 cm with plastic mulching. The results of the second field experiment showed that the optimal drip irrigation norm was 7200 m3 ha−1, with an irrigation water productivity of 8.76 kg m−3. The results of the field experiment showed that the optimal parameters for sugar beet in arid regions are 20 × 50 cm plant spacing with plastic mulching and a drip irrigation norm of 7200 m3 ha−1. The results of the research can be implemented in any other typical arid region. Copyright © 2016 John Wiley & Sons, Ltd.
